Soldering-iron



lTED STATES PATENT FFIQEO SOLDERlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 236,106, datedDecember'28, 1880.

Application filed November13, 1880. (ModeL) To all whom it may concern:

Be it known that I, VALENTIN S'roRoH, a citizen of the United States,residing at Knoxville borough,in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inSoldering- Irons; and I do hereby declare the followingto be a full,clear, and exact description of the invention, such as Will enableOthers skilled in the art to which it a 'ipertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures ofrefeience marked thereon, which form a part of thisspecification.

My invention relates to an improvement in soldering-irons; and itconsists in making the handle hollow to receive the oil, gasoline, orother fluid which is to be used for the purpose of heating the point,and placing a piston in this handle for the purpose of forcing the oilup to the burner.

It further consists in attaching a wire or a chain to each side of thepiston placed in the handle, and attaching one of the wires or chains toa spring mechanism for drawing the piston up into the handle, so as tocause it to force the oil out, and attaching the other Wire or chain toa drum or pulley in the lower end Cf the handle, whereby the piston canbe drawn down to the bottom of the handle, so as to allow the handle tobe filled, as will be more fully described hereinafter.

The object of my invention is to so construct a solderingiron thattheoil or other substance which is burned for the purpose of heating thepoint can be automatically fed to the burner, so as to keep up aconstantand uniform heat, and thus avoid the necessity ofconstantly having toput the iron in the fire for the purpose of reheating it.

Figure 1 is avertical longitudinal section of my invention. Figs. 2 and3 are detail views of the same.

A represents the handle, which is made hollow and somewhat larger thanusual, so as to receive the oil, gasoline, or other liquid which is tobe used for fuel in heating the point B by means of the burnerG. In thishandle is placed the piston D, which is packed so as to move air andwater tight, and which piston has secured to its upper side a wire,cord, or

chain, E. The outer end of this cord, wire, or chain has its end securedto a fusee or drum, F, of any suitable description, and which drum hassecured to its shaft a spring, G, for the purpose of keeping the cord,wire, or chain constantly wound upon the drum. This shaft is made squareat one end, so as to receive a key or device by means of which thespring can be unwound, and thus allow the piston to be drawn down to thebottom of the halide when so desired. This springis sufficiently strongto exert a powerful tension upon the piston, so that whenever the pistonis free to move the spring will draw it up into the tipmilled button, Z,by means of which the shaft is made to revolve. This shaft has anendwise movement, and has a contractile spring, 0, applied to it, so asto keep the shaft constantly'pressed outward, and thus prevent the wheelN from gearing with the wheel I until the shaft has been pushed inwardfor that purpose. Upon the outer end of the shaft, j ust inside ofthemilled button, is formed a ratchet, 2, and meshing with this ratchet ispressed outward to its full length by means of the spring 0 it will,when turned, revolve idly around; but when the shaft is pushed inwardand then turned to the right or left, accorda spring-dog, B. As longasthe shaft is ing to the pitch of the teeth, the Wheel N is go broughtin gear with the wheel I and the drum or pulley is made to revolve insuch a manner as to wind the cord, Wire, or chain upon it, and thus drawthe piston down into the lower end of the handle, for the purpose ofallowing the handle to be filled with the burning-fluid through theopening S in its upper end.

When it is desired to fill the handle with the burning-fluid the shaftis pushed inward,

ward to the right, the drum is made to wrap the wire, cord, or chainwhich is secured to the under side of the piston, and thus draw thepiston down into the bottom of the handle. The whole upper part of theiron above the handle is then unscrewed at S, so as to allow the fluidto be poured into it through the opening S, into which the part removedfits. Afterthe removed parthas been again screwed into position theshaftis pulled outward to release the drum or pulley F, and then thewhole power of the spring in the upper end of the handle is exerted indrawing the piston upward and forcing the burning-fluid up to theburner. While the wire, cord, or chain is wrapped upon the pulley I soas to hold the piston down into the lower end of the handle, the powerexerted by the spring Gr, operating through the gear-wheels l N andshaft L, is enough to cause suffieientfrietion between the ratchet 2 onthe shaft L and the spring-dog R to prevent the spring from forcing theshaft outward, so that whenever it is desired to stop the operation ofthe piston it is only necessary to force the shaft inward by hand anddraw the piston slightly backward by turning the end wheel or button,and then the piston will be held in this position until released by theniiovement of the shaft by the hand applied to the end wheel, Z. As thefluid is forced from the handle it passes through the pipe T, throughthe ring V, which surrounds the burner, and down through the pipe X tothe point at which the vapor is discharged into the burner. The fluid ispassed through the ring immediately around the burner for the purpose ofbeing heated by the flame, and thus vaporizing the fluid, so that itwill burn more readily. The heat from this burner, which may be of anydesired construction, heats the point B, so as to keep up a constant andsteady heat.

Having thus described my invention, I claim- 1. A soldering-iron havinga hollow handle to receive the burningfluid, in combination with apiston placed therein and a mechanism in each end of the handle for thepurpose of moving the piston back and forth, substantially as shown.

2. In a soldering-iron, the combination of a hollow handle, a pistonplaced therein, a spring, a drum, and a cord, wire, or chain forconnecting the piston to the drum, substantially as described.

3. In a soldering-iron, the combination of a hollow handle, a pistonplaced therein, a cord, wire, or chain secured to the piston, a drum orpulley for wrapping the cord, wire, or chain upon, and a mechanism forrevolving the pul- Icy, which mechanism can be thrown in and out of geartherewith, substantially as set forth.

4. In a soldering-iron, the combination of a hollow handle, a pistonplaced therein, and a mechanism for drawing the piston upward, so as toforce the fluid to the burner, with a burner which is connected to thehandle by means of suitable tubes or pipes, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
